Now, I think that is something of a misunderstanding of what ISA S88 is about, but it is understandable.

It is a misunderstanding because in fact the standard (part 1 at least) is only a guideline and does not say you must do all this, you can choose to exclude most of the possibilities in your own application.

But it is understandable because many 'S88' people push it too much, and furthermore they over complicate, seeming forgetting that the standard is supposed to make it easy for recipe designers.
